We decided to compare the two ends of the price list, beginning with a couple of flavoured tequilas at £3.25 a hit. Chilli tequila had a slightly itchy kick on the back of the throat and tasted of little else bar black pepper, while vanilla was agreeably smooth but, again, completely masked the natural taste of the spirit. The top end was worth every penny: the Porfidio anejos (£7.50) was as rich, velvety and downright delicious as the best malt whisky.
